IOG is 100% owner and operator of three fields in four licences the UK sector of the Southern North Sea collectively known as the Vulcan Satellites: -
|Nailsworth||P130 & P2342||48/25b & 48/25a|
Nailsworth was discovered with the 48/25a-4 well drilled by Shell/Exxon in 1987. Two further appraisal wells were drilled in 1989-90 and a further well, 48/25c-6, was drilled by Century Exploration in 2009. Elland was discovered with the 49/21b-10a well drilled by Silverstone Energy (now Verus Petroleum) in 2006 and lies adjacent to the producing Vulcan field which is operated by Conoco Phillips. Southwark was discovered with the 49/21-8a well drilled by Conoco in 2000.
The discoveries are all located in Permian age Rotliegendes Leman Sandstone with reservoir seal provided by the overlying Zechstein evaporates and carbonates. Reservoirs are typically tight and in common with other fields in the area benefit from hydraulic stimulation.
Reserves are estimated as follows: -

The Vulcan Satellites licences have the following current expiry dates:
|P130:||31 December 2021|
|P1915:||31 January 2020|
|P2342:||31 July 2019|
The fields lie approximately 30-45km east of IOG’s 100%-owned Blythe field and are ready for development with no further appraisal required.
A joint Phase 1 Field Development Plan comprising the development plans for Blythe, Elgood and Southwark was submitted to the UK Oil & Gas Authority in August 2018. First Gas from this Phase 1 development is targeted by end of Q2 2020.
As part of the acquisition of these assets, IOG assumed liability for the decommissioning of a suspended well on Elland.
The Environmental Impact Assessment for the Vulcan Satellites Hub development was submitted in April 2018.Vulcan Satellites Hub Environmental Impact Assessment
